对半刚接框架内填钢筋混凝土剪力墙的性能进行研究,制作2个比例尺为1∶3的1榀2层试件,一个试件带暗竖缝,另一个为实心内填墙,并施加反向循环侧向荷载。结果表明:2个试件均有足够的侧向刚度和强度抵抗侧移和侧向荷载。半刚接钢框架内填实心钢筋混凝土剪力墙由于后峰值强度退化,具有较好的延性和耗能能力。半刚接钢框架内填暗竖缝钢筋混凝土剪力墙延性更好,耗能能力也更好。因为一旦暗竖缝破坏,内填剪力墙就如柱一样工作,可提供延性,具有稳定的滞回性能。半刚接钢框架内填暗竖缝钢筋混凝土剪力墙能较好改善后峰值强度的退化程度。半刚接框架内填钢筋混凝土剪力墙震后易修复,可通过拆除严重破坏的墙并重新砌筑剪力墙,这是该结构的另一优点。
The performance of semi-rigid frame-infill reinforced concrete shear walls was studied. Two 1: 2 specimens with a scale of 1: 3 were made. One specimen had a dark vertical seam and the other was filled with solid wall. Apply reverse circulation side load. The results show that both specimens have sufficient lateral stiffness and strength to resist lateral displacement and lateral load. Semi-rigid steel frame filled with solid reinforced concrete shear wall due to post-peak strength degradation, has good ductility and energy dissipation. Semi-rigid steel frame filled with dark vertical seam reinforced concrete shear wall ductility better energy dissipation capacity is better. Because once the vertical joint damage, built-in shear wall works like a column can provide ductility, with a stable hysteretic performance. Semi-rigid steel frame filled with dark vertical seam reinforced concrete shear wall can better improve the degradation of peak intensity. Semi-rigid frame-framed Reinforced concrete shear walls are easily repaired after the earthquake, which is another advantage of the structure by removing the severely damaged wall and rebuilding the shear wall.
